Hopefully this is not to dated of a response. I have the same Pro 10 preamp that I took out of a closet after having been stored of about 15 years, cleaned the contacts and connected it last night. At first the right channel was lacking in high en response. I tried different input methods, changing cables and continued to have the same result. I then connected my output to the second set of preamp output and the proble went away. I guess its limited to the right channel on the preamp output A. Doesn't solve the problem but at least I am enjoying the preamp again.
Help with Vintage B&K Power/Pre Amps
I have a ST2140 power amp and a PRO 10MC Sonata Series preamp... thought I had trouble with one of my tweeters (right speaker sounding overly bright to the point of listening fatigue)... a friend brought over a pair of B&W monitors and after plugging them in, the right speaker had overly bright highs as well... anyone have any idea what might be causing this... do I need to send the 2140 into B&K to diagnose, or maybe the PRO 10MC, or both... any suggestions appreciated... this journey down the vintage equipment road can be challenging... thanks in advance.
